The Redskins still lack a solid offensive line and have an incomplete defense after the signing of DeSean Jackson, so adding an explosive receiver probably won't take them from three wins to the playoffs in one year.

But it could drastically change the stats for a few players in the NFC East.

On Wednesday, Vegas set a series of over/unders for Jackson's upcoming season.

The over/under on his yardage total is 1,000½. In six seasons, Jackson has topped 1,000 receiving yards three times.

For receptions, the over/under has been set at 72½ -- a mark Jackson has eclipsed just once in his six-year career. That was last season, when Jackson set a career-high with 82 receptions. Prior to that, he hadn't caught more than 62 passes in any year.

Jackson's over/under for total touchdowns -- not just receiving touchdowns -- is seven. Jackson had 10 total TDs in 2009, eight total TDs in 2010 and nine this past season. He fell well short in the other three seasons. Keep in mind that this over/under includes rushing TDs and punt return TDs.

With a mobile quarterback in Robert Griffin III, a proven running game with Alfred Morris and an underrated No. 1 receiver in Pierre Garcon running patterns on the opposite side of the field, Jackson should have plenty of opportunities to catch passes in space.

That could boost the numbers of Jackson's new teammates, which makes this final specialty bet intriguing...

Who will throw more TD passes in 2014: Nick Foles (-5) or RG3 (+5)?

If you take Foles, he must throw six-plus TD passes more than Griffin for you to win the bet. If you take RG3, he must be within five TD passes of Foles.

That's a tough one. The Redskins have been a run-based offense for two years and Griffin has averaged 18 TD passes over his first two seasons. Foles had 27 TD passes last season in just 13 games.

But things have changed. Foles no longer has his top deep threat. And RG3 goes from having an unhealthy Garcon in Year 1, to just Garcon in Year 2, to Garcon and Jackson in Year 3. Washington also has second-year tight end Jordan Reed, who showed flashes of promise in 2013, and signed Andre Roberts away from the Cardinals.
